IMPROVEMENT IN ADJUSTABLE SIGHTS FOR FIRE-ARMS.

Specification forming part of Letters Patent N0. 22,958, dated February 15, 1859.

To all whom it may concern:

Beit known that I, RICHARD S. LAWRENCE, of the city and county ofHartf0rd,in the State of Connecticut, have invented a new and improved method of constructing the rear barrelsight for fire-arms; and I do hereby declare that the following is a full and exact description.

The nature of my invention consists in a spring-base, the forward end of which I secure to the barrel with eithera stud or a screw. On the rearV end of said basespring I construct a hingejoint in connection with an elevator, so as to hold the elevator with the requisite firmness in either a perpendicular or horizontal position. At the .point of contiguity of said hinge-joint and the barrel I insert sufficiently firm in the metal of the barrel a stud or chair, which forms the hase for the joint to Work in, and with ears projecting upwardly of a size to cover and support the said hinge-joint at both ends thereof. The said stud or chair is so constructed that with proper force applied it can be moved in its base to the righ-t or to the left of the line of the bore of the barrel or be adjusted centrally with said line.`

For a more correct understanding ofthe nature of my invention,'[ would refer to the accompanying drawings, as part and parcel of this specification.

Figure l represents a lateral view of' my sight complete, and in form to attach to a gun barrel 5 Fi g2, a side view of a section of a gunbarrel with the sight attached and the elevator in a perpendicular position. a denotes the spring base or bed; B, the chair or stud; C,

chair or stud B; Fig. 12, an end view of the chair or stud.

I am aware of the construction of a sight by connecting an elevator with the barrel or with a fixed and inflexible base firmly secured to the barrel by a hinge, socket, or other joint, all of which I disclaim.

What I claim as my invention, and desire to secure by Letters Patent, is-

The application of said hinge-joint to the spring-base and elevator, constructed and arranged substantially as described.
